A triangular object, lit at all corners, seen travelling at great speed changes direction sharply without pausing or turning.

- It was fast, travelling somewhat low to the ground (~ 10,000 ft?).

- It was large and triangular in shape.

- It had blue/red lights on its corners (much like a plane, but they seemed brighter). All three corners were lit. The lights did not resemble plane lights that were observed in the minutes following when the sky was scanned for planes.

- It was flying North, then it SHARPLY changed direction to the North-East without slowing down or "turning" at all.

- It was completely silent (low-flying planes can be heard clearly even from indoors).

- It left no trail.

- It was seen through a window from indoors.

- It was about dusk when it was seen; its shape could be seen clearly, the sky was still somewhat light.

- It did not seem to fly anything like a plane (it was actually mistaken for an extremely fast and low-flying plane until it was seen changing direction so abruptly).
